FOLDING VEHICLE.

Application filed ombei 22. 1207.

To all whom it may concern: 1

States, and a resident New Rochelle, in the county of Westi c ester and State of New York, have ins vented a new and Improved Folding Vel hicle, of which the following is a full, clear, I

and erect description.

The invention relates to baby carriages,

stance, as shown and describedin the Letters Patent of the United States, No. 863,972,

granted to Robert J. Ehlers on August 20, 1907.

The object of the invention is to folding vehicle, arranged to permit of conveniently folding the vehicle into a small parcel, for conveniently carrying it about from place to place, and to a low extending the vehicle and securely locking the parts in the extended position whenever it is desired to use the vehicle for its legitimate purposes. i The invention consistsof novel features I provide and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawart of this specification, in which similar 0 aracters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improveposition; Fig. 2 is a like view of the same in a-iolded condition; Fig. 3 is an under side view of the same; Fig. 4 is a perspective view of the. bed, the pivoted wheel supports and the cam device for actuating the wheel supports; Fig. 5 is an en 'larged sectional side elevation of the fasten- I device for holding a wheel to its axle, and 4 Fig. 6 is a transverse section of the same.

The bed of the vehicle consists preferably of twosnaced side bars A, comiected with each other by cross bars A, so as to. render the .bed as rigid as possible. The are. arranged in such a carries the front and rear wheel of one side of the vehicle, that is, the wheel support B. carries the front and rear wheels 0, C of the left side. of the vehicle, sup on B carries the front C 3 of the right-hand side manner that each and rear-wheels of the vehicle.

Specification of Letters Patent;

. vehicle bet wheel support provided 7 on the top of the wheel Patented Jan. 19, 1909; Serial No. eeasez.

The wheel supports B and B are pivoted brackets A A arran ed on the side bars A, A of the bed of the ve icle, so as to allow: the wheel supports B and Bto swing trans versely with a view to hold the same on the under side of the bed, as indicatedin Figs. 2- and 3. The wheel supports B and B are actuated from the handle D, having the terminals of its side arms pivoted at D on'the" outer ends of the side-bars A and A of the and the said side arms of the handleD are pivotally connected by-for' wardly. extending links E with the upper ends of a-U-shaped lever-F, fulcrumedat F and F on the side bars A and A, as plainly shown in 4. The lever F is provide'd with'rounded ofl cam portions'F Ft, engaging longitudinally extending slots B B formed on the, wheel supports B and B, so that when the several parts are in an extended position, as illustrated in Fig. 1, and '75 the operator swings the handle D forward in the direction ofthe arrow a, thcna swinging motion is given by the links E to-the lever F, to swin the cam portions F F"rear-' wardly in t e direction of the arrow- 6 (see- Fig, 1), whereby an'inward swinging move ment is given to the wheel supports B- and B, to fold the latter onto the under side of the bed of the vehicle, as illustrated in Figs.- 2 and 3.

B3; reference to Fig. 4, it will be seen=that the curvature of the cam portions F and F 4 is diiierent, that is, the curvature of'the cam portion F is more steep than thatof the on tion F whereby the wheel support is swung into a folded position ahead of the B, that is, the wheel supports B and B are swung successively into a folded position, or from the latter back into an extended osition. The lever F is further VlYitl shoulders F adapted to rest supports B and B at the time the latter are in an extended position, and the lever F is inclined, as shown in Fig. 1, that is, the shoulders F 5 together withthe cam ortions F F" are somewhat in advance of t e pivots F and F j N ow by this arrangement the Wheel supports B and Band the lever F are firmly held in a locked position, to prevent accidental folding of the wheelsupports while the vehicle is in use for its legitimate purpose. In order to secure the handle D, however, and. -consequently 1 carried by the bed oft .portions being shaped to swing one o the lever F and the wheel supports B and B an in an extended position, sectional braces H are provided, votally connectin the side arms A, A wit the side arms of t e handle D. The seat I of the vehicle is provided with a suitable back I and a foot rest I, and the said seat. Iis preferably su ported on springs e vehicle.

By reference to Fig. 1, it will be seen that the upper portions of the side arms of the U- shapedleverfF as well as the links E, form the foldable sides of the vehicle, it being understood that the links E fold down upon the bed when the handle D is swung forward, as previously explained for folding the wheel supports B and B. The axle J for each of the wheels 0, C, G and'G is provided with an annular groove J, into which projects a in K heldon a springclamp K, adapted to clamp the hub C of agvehicle wheel O, O, C or C .By. wheel is held against movement in the direction of its axis, but is free to turn onithe axle J, and further fastening devices, such as the nuts and collars usually employed for holding the wheel in place on an axle, are entirely dispensed with. It will alsobe/noticed that the groove J serves to retain thelubricant 1n the axle, so as to properly lubricate 'the wheel, at all times. Having thus deseribedmy invention, I

claim-as new and desire 'tosecure by Letters,

Patent:

1. A foldingvehicle, comprising spaced side bar's,'crossbars connecting the side bars,

a wheel support pivoted to each side bar to swing transverselythereof, a substantially U-shape handle having the terminals of its side arms pivoted to the outer endsof the side bars, forwardly extending links pivoted to the handle, a U-shape lever having its side arms pivoted to the links, the said side arms being provided with cam portions the wheel support hav-ing longitudinal slots through which said cam portions extend, thefcalrln t e this arrangement the vehicle ports previous to the swinging of the ot er, whereby to fold the wheel supports in succession.

' 2. A folding vehicle comprising a bed, wheel supports mounted to swing transversely on the said bed and each carrying the wheels of oneside of the vehicle, the said wheel supports having longitudinal slots, a handle mounted to swing longitudinally on the said bed, and a lever controlled by the said handle and having cam portions for engaging the said slots, one of said cam portions being more abrupt than the others whereby to operate the supports successively.

3. A folding vehicle comprising a wheel supports mounted to swing transversely on the said bed and each carrying the wheels of one side of the vehicle, the said wheel supports having longitudinal slots, a handle mounted to swing longitudinally on the said bed, and a lever controlledby the said handle and having a U-shaped portion whose arms engage the respective slots, said arms being of difierent's ape whereby to swing the wheel supports successively.

4. A folding vehicle comprising a bed, wheel supports mounted to swing transversely on the said bed and each carrying the wheels of one side of the vehicle, the said wheel supports handle mounted to swing longitudinally on the said bed, and a lever controlled by the said handle and having a U-shaped portion engaging the said slots, the sides of the U- shaped portion having different curvatures, to cause the said wheel supports to swing in succession into a folded or extended position relative to the said bed.

In testimony whereof I have signed my name to this specification in the presence of JAMES A. GRAY, Roar. J. Eniinns.
